Prep your PDA for travel
The success of the iPhone and its “application store” has spawned a new era for those on the go—and copycat cell-phone companies are clamoring to add similar capabilities. Among the more than 3,000 iPhone applications available, there’s Urbanspoon, which provides restaurant recommendations in your neighborhood; iWant, which lets you search for everything from cocktail lounges to antiques shops and then plot the places on a map; and iLingo, which allows you to download hundreds of useful phrases in several European and Asian languages. Airline companies are also hopping on the mobile bandwagon. With Southwest, Delta, and American, you can check in from your PDA. Other airlines will soon follow suit.
